Biocide compositions comprising glycerol(ether)phosphates

ABSTRACT

Suggested are biocide compositions, comprising (a) Glycerol(ether)phosphates; (b) Biocides and optionally (c) Oil components or co-solvents and/or (d) Emulsifiers. The compositions show excellent adjuvant and complexing properties.

FIELD OF THE INVENTION

The present invention relates to the area of agrochemicals and refers tobiocide compositions comprising glycerol(ether)phosphates and their useas adjuvants or sequestrants for biocides.

BACKGROUND OF THE INVENTION

Biocides, and in particular pesticides such as fungicides, insecticidesand herbicides, are important auxiliary agents for agriculture in orderto protect crops and to increase their quality and harvest yield.Depending on the various and often very specific needs, a magnitude ofactives exist showing very different chemical structures and behaviours.Nevertheless, it is well known from the state of the art that it remainsdifficult to prepare solid or even liquid compositions of these activeswhich are exhibiting a satisfying stability, especially if stored atvery low or elevated temperatures over a longer period. In addition tostorage stability and the ability to prepare stable tank mixes, theinfluence of additives and adjuvants on bioperformance is of elevatedimportance. Their choice is governed by many additional parameters, suchas ease to manufacture, a low toxicological and ecotoxicologicalprofile, their compatibility such formulations such as emulsifiableconcentrates (EC), oil in water emulsions (EW), suspo-emulsions (SE) andconcentrated suspensions in water (SC) or in oil (OD)

In this context reference is made to EP 0645962 B1 (Nanomura) disclosinga sprinkling foliage with aqueous solutions of methanol, said solutionoptionally containing glycine or glycerophosphates. EP 2130435 A1 (CosmoOil) specifically refers to an agent for improving alkali resistance ofa plant, which is characterized by containing 5-aminolevulinic acid, aderivative thereof or a salt of any of them, and for example an ironsalt of a glycerol phosphate.

The problem underlying the present invention has been to overcome thedisadvantages of the state of the art. In particular it has been theobject to provide new additives for agricultural compositions fulfillinga complex profile of application requirements: adjuvant properties inorder to support and increase the performance of the biocides within thecompositions, high stability of the compositions also over longerstorage times and different storage temperatures, compatibility with awide range of biocides, and low foaming behavior, and in particular highability for complexing hard water cations.

DETAILED DESCRIPTION OF THE INVENTION

The present invention refers to biocide compositions, comprising

-   -   (a) Glycerol(ether)phosphates,    -   (b) Biocides and optionally    -   (c) Oil components and/or co-solvents and/or    -   (d) Emulsifiers.

Surprisingly it has been observed that glycerol phosphates and glycerolether phosphates are low foaming surfactants, exhibiting high adjuvantperformance and in particular represent excellent sequestration agentsfor hard water cations. The products improve the weed control propertiesof many aqueous biocide formulations, especially of glyphosate,containing calcium and/or magnesium ions. Compositions comprisingglycerol(ether) phosphates also exhibit a better storage stability whencompared especially with tallow amine ethoxylates.

Glycerol(Ether)Phosphates

Glycerol phosphates and glycerol ether phosphates are obtainableaccording to standard procedures of organic chemistry. Typically,glycerol or adducts of alkylene oxide to glycerol are reacted with P₂O₅or polyphosphoric acid to provide statistical mixtures of mono-, di- andtriphosphates or ether phosphates, following general formula (I)

In which R¹ and R² independently from each other represent eitherhydrogen or a (PO₃X) group, AO means an ethylene oxide, a propyleneoxide, a butylene oxide unit or their mixtures, X stands for hydrogen,an alkali metal, alkaline earth metal, ammonium, alkyl ammonium orGlucammonium and the sum (x+y+z) either stands for zero or an integer offrom 1 to 50. The ratio of mono/di/triphosphates mainly depends onreaction conditions and stoichiometric ratios. Typically the mono/di/triratio is 1:(1-5):(1-5). In a first preferred embodiment saidglycerol(ether)phosphates represent either sodium, potassium, or inparticular ammonium salts. In another preferred embodiment the glycerolether phosphates comprise 1 to 50, preferably 2 to 30 and morepreferably 5 to 20 mol ethylene oxide, propylene oxide and/or butyleneoxide units per hydroxyl group in the glycerol moiety. In particularpreferred are glycerol polyethylene glycol ether phosphates, glycerolpolypropylene glycol ether phosphates and glycerolpolyethylene/propylene glycol ether phosphates, the latter showingeither a block or random distribution of the alkylene oxide groups.

Biocides

A biocide, also called bio-active agent (component b) in the context ofthe present invention is a plant protection agent, more particular achemical substance capable of killing different forms of livingorganisms used in fields such as medicine, agriculture, forestry, andmosquito control. Also counted under the group of biocides are so-calledplant growth regulators.

Usually, biocides are divided into two sub-groups:

-   -   pesticides, which includes fungicides, herbicides, insecticides,        algicides, moluscicides, miticides and rodenticides, (here, The        Pesticide Manual, 14^(th) edition, BCPC 2006 is included as a        reference, it provides information about the individual mode of        actions of active ingredients) and    -   antimicrobials, which includes germicides, antibiotics,        antibacterials, antivirals, antifungals, antiprotozoals and        antiparasites.

Biocides can also be added to other materials (typically liquids) toprotect the material from biological infestation and growth. Forexample, certain types of quaternary ammonium compounds (quats) can beadded to pool water or industrial water systems to act as an algicide,protecting the water from infestation and growth of algae.

a) Pesticides

The U.S Environmental Protection Agency (EPA) defines a pesticide as“any substance or mixture of substances intended for preventing,destroying, repelling, or mitigating any pest”. A pesticide may be achemical substance or biological agent (such as a virus or bacteria)used against pests including insects, plant pathogens, weeds, mollusks,birds, mammals, fish, nematodes (roundworms) and microbes that competewith humans for food, destroy property, spread disease or are anuisance. In the following examples, pesticides suitable for theagrochemical compositions according to the present invention are given:

b) Fungicides

A fungicide is one of three main methods of pest control—the chemicalcontrol of fungi in this case. Fungicides are chemical compounds used toprevent the spread of fungi in gardens and crops. Fungicides are alsoused to fight fungal infections. Fungicides can either be contact orsystemic. A contact fungicide kills fungi when sprayed on its surface. Asystemic fungicide has to be absorbed by the fungus before the fungusdies.

An herbicide is a pesticide used to kill unwanted plants. Selectiveherbicides kill specific targets while leaving the desired croprelatively unharmed. Some of these act by interfering with the growth ofthe weed and are often based on plant hormones. Herbicides used to clearwaste ground are nonselective and kill all plant material with whichthey come into contact. Herbicides are widely used in agriculture and inlandscape turf management. They are applied in total vegetation control(TVC) programs for maintenance of highways and railroads.

An insecticide is a pesticide used against insects in all developmentalforms. They include ovicides and larvicides used against the eggs andlarvae of insects. Insecticides are used in agriculture, medicine,industry and the household. In the following, suitable chemical classesand examples of insecticides are mentioned:

Plant hormones (also known as phytohormones) are chemicals that regulateplant growth. Plant hormones are signal molecules produced within theplant, and occur in extremely low concentrations. Hormones regulatecellular processes in targeted cells locally and when moved to otherlocations, in other locations of the plant. Plants, unlike animals, lackglands that produce and secrete hormones. Plant hormones shape theplant, affecting seed growth, time of flowering, the sex of flowers,senescence of leaves and fruits. They affect which tissues grow upwardand which grow downward, leaf formation and stem growth, fruitdevelopment and ripening, plant longevity and even plant death. Hormonesare vital to plant growth and lacking them, plants would be mostly amass of undifferentiated cells. In the following, suitable plant growthregulators are mentioned:

-   -   Aviglycine,    -   Cyanamide,    -   Gibberellins such gibberellic acid,    -   Quaternary ammoniums such as chlormequat chloride, mepiquat        chloride,    -   Ethylene generators such ethephone,        f) Rodenticides

Rodenticides are a category of pest control chemicals intended to killrodents. Rodents are difficult to kill with poisons because theirfeeding habits reflect their place as scavengers. They would eat a smallbit of something and wait, and if they do not get sick, they wouldcontinue eating. An effective rodenticide must be tasteless and odorlessin lethal concentrations, and have a delayed effect. In the following,examples for suitable rodenticides are given:

Anticoagulants are defined as chronic (death occurs after 1-2 weeks postingestion of the lethal dose, rarely sooner), single-dose (secondgeneration) or multiple dose (first generation) cumulative rodenticides.Fatal internal bleeding is caused by lethal dose of anticoagulants suchas brodifacoum, coumatetralyl or warfarin. These substances in effectivedoses are antivitamins K, blocking the enzymes K₁-2,3-epoxide-reductase(this enzyme is preferentially blocked by4-hydroxycoumarin/4-hydroxythiacoumarin derivatives) andK₁-quinone-reductase (this enzyme is preferentially blocked byindandione derivatives), depriving the organism of its source of activevitamin K₁. This leads to a disruption of the vitamin K cycle, resultingin an inability of production of essential blood-clotting factors(mainly coagulation factors II (prothrombin), VII (proconvertin), IX(Christmas factor) and X (Stuart factor)). In addition to this specificmetabolic disruption, toxic doses of4-hydroxycoumarin/4-hydroxythiacoumarin and indandione anticoagulantsare causing damage to tiny blood vessels (capillaries), increasing theirpermeability, causing diffuse internal bleedings (haemorrhagias). Theseeffects are gradual; they develop in the course of days and are notaccompanied by any nociceptive perceptions, such as pain or agony. Inthe final phase of intoxication the exhausted rodent collapses inhypovolemic circulatory shock or severe anemia and dies calmly.Rodenticidal anticoagulants are either first generation agents(4-hydroxycoumarin type: warfarin, coumatetralyl; indandione type:pindone, diphacinone, chlorophacinone), generally requiring higherconcentrations (usually between 0.005 and 0.1%), consecutive intake overdays in order to accumulate the lethal dose, poor active or inactiveafter single feeding and less toxic than second generation agents, whichare derivatives of 4-hydroxycoumarin (difenacoum, brodifacoum,bromadiolone and flocoumafen) or 4-hydroxy-1-benzothiin-2-one(4-hydroxy-1-thiacoumarin, sometimes incorrectlly referred to as4-hydroxy-1-thiocoumarin, for reason see heterocyclic compounds), namelydifethialone. Second generation agents are far more toxic than firstgeneration agents, they are generally applied in lower concentrations inbaits (usually in the order of 0.001-0.005%), and are lethal aftersingle ingestion of bait and are effective also against strains ofrodents that have become resistant against first generationanticoagulants; thus the second generation anticoagulants are sometimesreferred to as “superwarfarins”. Sometimes, anticoagulant rodenticidesare potentiated by an antibiotic, most commonly by sulfaquinoxaline. Theaim of this association (e.g. warfarin 0.05%+sulfaquinoxaline 0.02%, ordifenacoum 0.005%+sulfaquinoxaline 0.02% etc.) is that theantibiotic/bacteriostatic agent suppresses intestinal/gut symbioticmicroflora that represents a source of vitamin K. Thus the symbioticbacteria are killed or their metabolism is impaired and the productionof vitamin K by them is diminuted, an effect which logically contributesto the action of anticoagulants. Antibiotic agents other thansulfaquinoxaline may be used, for example co-trimoxazole, tetracycline,neomycin or metronidazole. A further synergism used in rodenticidalbaits is that of an association of an anticoagulant with a compound withvitamin D-activity, i.e. cholecalciferol or ergocalciferol (see below).A typical formula used is, e.g., warfarin 0.025-0.05%+cholecalciferol0.01%. In some countries there are even fixed three-componentrodenticides, i.e. anticoagulant+antibiotic+vitamin D, e.g. difenacoum0.005%+sulfaquinoxaline 0.02%+cholecalciferol 0.01%. Associations of asecond-generation anticoagulant with an antibiotic and/or vitamin D areconsidered to be effective even against the most resistant strains ofrodents, though some second generation anticoagulants (namelybrodifacoum and difethialone), in bait concentrations of 0.0025-0.005%are so toxic that no known resistant strain of rodents exists and evenrodents resistant against any other derivatives are reliablyexterminated by application of these most toxic anticoagulants.

Vitamin K₁ has been suggested and successfully used as an antidote forpets or humans, which/who were either accidentally or intentionally(poison assaults on pets, suicidal attempts) exposed to anticoagulantpoisons. In addition, since some of these poisons act by inhibitingliver functions and in progressed stages of poisoning, severalblood-clotting factors as well as the whole volume of circulating bloodlacks, a blood transfusion (optionally with the clotting factorspresent) can save a person's life who inadvertently takes them, which isan advantage over some older poisons.

Metal phosphides have been used as a means of killing rodents and areconsidered single-dose fast acting rodenticides (death occurs commonlywithin 1-3 days after single bait ingestion). A bait consisting of foodand a phosphide (usually zinc phosphide) is left where the rodents caneat it. The acid in the digestive system of the rodent reacts with thephosphide to generate the toxic phosphine gas. This method of vermincontrol has possible use in places where rodents are resistant to someof the anticoagulants, particularly for control of house and field mice;zinc phosphide baits are also cheaper than most second-generationanticoagulants, so that sometimes, in cases of large infestation byrodents, their population is initially reduced by copious amounts ofzinc phosphide bait applied, and the rest of the population thatsurvived the initial fast-acting poison is then eradicated by prolongedfeeding on anticoagulant bait. Inversely, the individual rodents thatsurvived anticoagulant bait poisoning (rest population) can beeradicated by pre-baiting them with nontoxic bait for a week or two(this is important to overcome bait shyness, and to get rodents used tofeeding in specific areas by offering specific food, especially wheneradicating rats) and subsequently applying poisoned bait of the samesort as used for pre-baiting until all consumption of the bait ceases(usually within 2-4 days). These methods of alternating rodenticideswith different modes of action provides a factual or an almost 100%eradication of the rodent population in the area if theacceptance/palatability of bait is good (i.e., rodents readily feed onit).

Phosphides are rather fast acting rat poisons, resulting in that therats are dying usually in open areas instead of the affected buildings.Typical examples are aluminum phosphide (fumigant only), calciumphosphide (fumigant only), magnesium phosphide (fumigant only) and zincphosphide (in baits). Zinc phosphide is typically added to rodent baitsin amounts of around 0.75-2%. The baits have a strong, pungentgarlic-like odor characteristic for phosphine liberated by hydrolysis.The odor attracts (or, at least, does not repulse) rodents, but has arepulsive effect on other mammals; birds, however (notably wildturkeys), are not sensitive to the smell and feed on the bait thusbecoming collateral damage.

Hypercalcemia. Calciferols (vitamins D), cholecalciferol (vitamin D₃)and ergocalciferol (vitamin D₂) are used as rodenticides, which aretoxic to rodents for the same reason that they are beneficial tomammals: they are affecting calcium and phosphate homeostasis in thebody. Vitamins D are essential in minute quantities (few IUs perkilogram body weight daily, which is only a fraction of a milligram),and like most fat soluble vitamins they are toxic in larger doses asthey readily result in the so-called hypervitaminosis, which is, simplysaid, poisoning by the vitamin. If the poisoning is severe enough (thatis, if the dose of the toxicant is high enough), it eventually leads todeath. In rodents consuming the rodenticidal bait it causeshypercalcemia by raising the calcium level, mainly by increasing calciumabsorption from food, mobilising bone-matrix-fixed calcium into ionisedform (mainly monohydrogencarbonate calcium cation, partially bound toplasma proteins, [CaHCO₃]⁺), which circulates dissolved in the bloodplasma, and after ingestion of a lethal dose the free calcium levels areraised sufficiently so that blood vessels, kidneys, the stomach wall andlungs are mineralised/calcificated (formation of calcificates, crystalsof calcium salts/complexes in the tissues thus damaging them), leadingfurther to heart problems (myocard is sensitive to variations of freecalcium levels that are affecting both myocardial contractibility andexcitation propagation between atrias and ventriculas) and bleeding (dueto capillary damage) and possibly kidney failure. It is considered to besingle-dose, or cumulative (depending on concentration used; the common0.075% bait concentration is lethal to most rodents after a singleintake of larger portions of the bait), sub-chronic (death occurringusually within days to one week after ingestion of the bait). Appliedconcentrations are 0.075% cholecalciferol and 0.1% ergocalciferol whenused alone. There is an important feature of calciferols toxicologywhich is that they are synergistic with anticoagulant toxicants. Thismeans that mixtures of anticoagulants and calciferols in the same baitare more toxic than the sum of toxicities of the anticoagulant and thecalciferol in the bait so that a massive hypercalcemic effect can beachieved by substantially lower calciferol content in the bait andvice-versa. More pronounced anticoagulant/hemorrhagic effects areobserved if calciferol is present. This synergism is mostly used inbaits low in calciferol because effective concentrations of calciferolsare more expensive than effective concentrations of most anticoagulants.The historically very first application of a calciferol in rodenticidalbait was, in fact, the Sorex product Sorexa® D (with a different formulathan today's Sorexa® D) back in the early 1970's, containing warfarin0.025%+ergocalciferol 0.1%. Today, Sorexa® CD contains a 0.0025%difenacoum+0.075% cholecalciferol combination. Numerous other brandproducts containing either calciferols 0.075-0.1% (e.g. Quintox®,containing 0.075% cholecalciferol) alone, or a combination of calciferol0.01-0.075% with an anticoagulant are marketed.

g) Miticides, Moluscicides and Nematicides

Miticides are pesticides that kill mites. Antibiotic miticides,carbamate miticides, formamidine miticides, mite growth regulators,organochlorine, permethrin and organophosphate miticides all belong tothis category. Molluscicides are pesticides used to control mollusks,such as moths, slugs and snails. These substances include metaldehyde,methiocarb and aluminium sulfate. A nematicide is a type of chemicalpesticide used to kill parasitic nematodes (a phylum of worm). Anematicide is obtained from a neem tree's seed cake; which is theresidue of neem seeds after oil extraction. The neem tree is known byseveral names in the world but was first cultivated in India sinceancient times.

-   -   active chlorine (i.e., hypochlorites, chloramines,        dichloroisocyanurate and trichloroisocyanurate, wet chlorine,        chlorine dioxide, etc.),    -   active oxygen (peroxides such as peracetic acid, potassium        persulfate, sodium perborate, sodium percarbonate and urea        perhydrate),    -   iodine (iodpovidone (povidone-iodine, Betadine), Lugol's        solution, iodine tincture, iodinated nonionic surfactants),    -   concentrated alcohols (mainly ethanol, 1-propanol, called also        n-propanol and 2-propanol, called isopropanol and mixtures        thereof; further, 2-phenoxyethanol and 1- and 2-phenoxypropanols        are used),    -   phenolic substances (such as phenol (also called “carbolic        acid”), cresols (called “Lysole” in combination with liquid        potassium soaps), halogenated (chlorinated, brominated) phenols,        such as hexachlorophene, triclosan, trichlorophenol,        tribromophenol, pentachlorophenol, Dibromol and salts thereof),    -   cationic surfactants such as some quaternary ammonium cations        (such as benzalkonium chloride, cetyl trimethylammonium bromide        or chloride, didecyldimethylammonium chloride, cetylpyridinium        chloride, benzethonium chloride) and others, non-quarternary        compounds such as chlorhexidine, glucoprotamine, octenidine        dihydrochloride, etc.),    -   strong oxidizers such as ozone and permanganate solutions;    -   heavy metals and their salts such as colloidal silver, silver        nitrate, mercury chloride, phenylmercury salts, copper sulfate,        copper oxide-chloride etc. Heavy metals and their salts are the        most toxic and environmentally hazardous bactericides and,        therefore, their use is strongly suppressed or forbidden;        further, also    -   properly concentrated strong acids (phosphoric, nitric,        sulfuric, amidosulfuric, toluenesulfonic acids) and    -   alcalis (sodium, potassium, calcium hydroxides) between pH<1        or >13, particularly below elevated temperatures (above 60° C.)        kill bacteria.

As antiseptics (i.e., germicide agents that can be used on human oranimal body, skin, mucoses, wounds and the like), few of the abovementioned disinfectants can be used under proper conditions (mainlyconcentration, pH, temperature and toxicity toward man/animal). Amongthem, important are

-   -   Some properly diluted chlorine preparations (e.g. Daquin's        solution, 0.5% sodium or potassium hypochlorite solution,        pH-adjusted to pH 7-8, or 0.5-1% solution of sodium        benzenesulfochloramide (chloramine B)), some    -   iodine preparations such as iodopovidone in various galenics        (ointments, solutions, wound plasters), in the past also Lugol's        solution,    -   peroxides as urea perhydrate solutions and pH-buffered 0.1-0.25%        peracetic acid solutions,    -   alcohols with or without antiseptic additives, used mainly for        skin antisepsis,    -   weak organic acids such as sorbic acid, benzoic acid, lactic        acid and salicylic acid    -   some phenolic compounds such as hexachlorophene, triclosan and        Dibromol, and    -   cation-active compounds such as 0.05-0.5% benzalkonium, 0.5-4%        chlorhexidine, 0.1-2% octenidine solutions.

Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics onlyslow down their growth or reproduction. Penicillin is a bactericide, asare cephalosporins. Aminoglycosidic antibiotics can act in both abactericidic manner (by disrupting cell wall precursor leading to lysis)or bacteriostatic manner (by connecting to 30 s ribosomal subunit andreducing translation fidelity leading to inaccurate protein synthesis).Other bactericidal antibiotics according to the present inventioninclude the fluoroquinolones, nitrofurans, vancomycin, monobactams,co-trimoxazole, and metronidazole Preferred actives are those withsystemic or partially systemic mode of action such as for exampleazoxystrobin.
